pacemaker: 2.0.0 to 2.0.1 compatibility report

Note: This particular run has many false positives due to changes in how the report was generated beginning with 2.0.1. The ABI is believed to be fully compatible from 2.0.0 to 2.0.1.

Problems with Data Types, Low Severity 15

	Change	Effect
1	Size of this type has been changed from 48 bytes to 64 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Base type of field active has been changed from gboolean()(int, gboolean) to gboolean()(pe_resource_t, gboolean).	Replacement of field base type may indicate a change in the semantic meaning of the field.
3	Base type of field free has been changed from *void()(int)* to *void()(pe_resource_t)*.	Replacement of field base type may indicate a change in the semantic meaning of the field.
4	Base type of field print has been changed from void()(int, char const, long, void) to void()(pe_resource_t, char const, long, void).	Replacement of field base type may indicate a change in the semantic meaning of the field.
5	Base type of field state has been changed from enum rsc_role_e()(int const, gboolean) to enum rsc_role_e()(pe_resource_t const, gboolean).	Replacement of field base type may indicate a change in the semantic meaning of the field.
6	Base type of field unpack has been changed from gboolean()(int, int) to gboolean()(pe_resource_t, pe_working_set_t).	Replacement of field base type may indicate a change in the semantic meaning of the field.
7	Field parameter became const.	The value of this field is expected to be const in new library version, but can be modified by old applications.
8	The pointer level of field parameter has been decreased from 2 to 1.	The library functions will treat the value of this field as the lower-dimension array and will not read all elements. This may change the behavior of applications.
9	Type of field parameter has been changed from char** to char()(pe_resource_t, pe_node_t, gboolean, char const, pe_working_set_t).	Replacement of the field data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Field pending_node has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Size of this type has been changed from 296 bytes to 288 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
3	Type of field variant has been changed from enum pe_obj_types to int.	Replacement of the field data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Field param_check has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Field stop_needed has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
3	Size of this type has been changed from 224 bytes to 240 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
